Detailed Description

Performs a simple reverb effect on a stream of audio data.

This is a simple stereo reverb, based on the technique and tunings used in FreeVerb. Use setSampleRate() to prepare it, and then call processStereo() or processMono() to apply the reverb to your audio data.

inlinenoexcept

Returns the reverb's current parameters.

processMono()

void Reverb::processMono ( float *const  samples, const int  numSamples  )

inlinenoexcept

Applies the reverb to a single mono channel of audio data.

References allPass, comb, Reverb::Parameters::damping, dryGain, feedback, gain, juce::LinearSmoothedValue< FloatType >::getNextValue(), jassert, numAllPasses, numCombs, and wetGain1.

processStereo()

void Reverb::processStereo ( float *const  left, float *const  right, const int  numSamples  )

inlinenoexcept

Applies the reverb to two stereo channels of audio data.

reset()

void Reverb::reset ( )

inline

Clears the reverb's buffers.

setDamping()

Referenced by updateDamping().

setParameters()

void Reverb::setParameters ( const Parameters &  newParams )

inline

Applies a new set of parameters to the reverb.

Note that this doesn't attempt to lock the reverb, so if you call this in parallel with the process method, you may get artifacts.

References dryGain, Reverb::Parameters::dryLevel, Reverb::Parameters::freezeMode, gain, isFrozen(), parameters, juce::LinearSmoothedValue< FloatType >::setValue(), updateDamping(), wetGain1, wetGain2, Reverb::Parameters::wetLevel, and Reverb::Parameters::width.

setSampleRate()

void Reverb::setSampleRate ( const double  sampleRate )

inline

Sets the sample rate that will be used for the reverb.

You must call this before the process methods, in order to tell it the correct sample rate.
